Specific embodiment

Present invention is further described in detail with specific embodiment with reference to the accompanying drawing: referring to Fig. 1 to Fig. 4, toothbrush, Including shell 1, mobile jib 2 is provided in the shell 1, the mobile jib 2 has the one end 20 for stretching out the shell, in the one end Toothbrush head 100 is arranged on 20, so that the vibration that mobile jib 2 generates is transferred on toothbrush head 100 by the one end 20.

Permanent magnet 21, the setting of permanent magnet 21 described in the side interval of the permanent magnet 21 are provided in the middle part of the mobile jib 2 There is coil block 3, the coil block 3 is electrically connected with control circuit board (attached drawing is not shown) and battery component 200, in the shell The upper end of body is provided with turnbarrel 4, and the coil block 3 is fixedly connected with the turnbarrel 4 by a connecting rod 300, The turnbarrel 4 can be rotated from first position to the second position, and the locking on the first position and the second position；Institute When stating turnbarrel 4 and being in first position, permanent magnet 21 of the coil block 3 on the mobile jib 2 on the turnbarrel 4 is applied The active force for adding horizontal direction, at 4 second position of turnbarrel, coil block 3 on the turnbarrel 4 is to described Permanent magnet 21 on mobile jib 2 applies the active force of vertical direction (herein horizontally and vertically with respect to brush head, such as water Square to refer to brush head).Turnbarrel quilt can be effectively prevented far from hand grip position in the upper end that shell is arranged in turnbarrel Transmitting of the vibration to hand holding part position in maloperation and turnbarrel.

Wherein, coil block 3 and control circuit board (existing structure, attached to be not shown in the figure) and battery component 200 are electrically connected, Square-wave pulse by changing coil block 3 changes polarity, and the pole N, S alternate oscillation magnetic field is generated in coil, when will be described For the rotation of turnbarrel 4 to when being located at first position, the alternate oscillation magnetic field that coil block 3 generates at this time forces the permanent magnet 21 Mobile jib 2 is driven to generate swinging back and forth for horizontal direction, therefore, toothbrush obtains higher cleaning dynamics.When by the turnbarrel 4 To when being located at the second position, the alternate oscillation magnetic field that coil block 3 generates at this time forces the permanent magnet 21 to drive mobile jib for rotation Swinging back and forth for vertical direction is generated, therefore, toothbrush obtains higher massage effect.

As a kind of specific structure by the turnbarrel 4 in first position and second position locking, in the rotation Steel ball locating slot 41 is set on the end face of sleeve 4, is provided with steel ball 40 in the steel ball locating slot 41, is positioned in the steel ball The elastic component 42 of steel ball 40 described in fexible bias pressure is provided in slot 41, in the end face of the shell 1 and the turnbarrel 4 cooperation On be provided with the steel ball cooperation limiting slot 11.Above structure turns to first position and second in turnbarrel 4 When setting, the steel ball 40 enters in the limiting slot 11 and then realizes turnbarrel 4 in the locking of above-mentioned position, in turnbarrel When 4 rotation, steel ball is then abutted against to entering in steel ball locating slot 41, and the rotation of turnbarrel 4 will not be interfered at this time.When The locking mode of the turnbarrel 4 is not specifically limited in right the application, locking mode may be set to be other existing Some structures.

The tail end of the mobile jib 2 is fixedly installed a pilot pin 5, and pilot pin 5 is a cylindrical shape structure, the pilot pin 5 one end is fixedly connected with the shell.By the setting of pilot pin 5, so that being located at first position using water in turnbarrel 4 Square to swing back and forth mode when and turnbarrel 4 be located at the second position using vertical direction swing back and forth mode when, Mobile jib 2 can return back to initial position under the active force of pilot pin 5.

Since pilot pin 5 is during being chronically at both of which switchover operation, and being also easy to produce metal fatigue causes it solid There is coefficient to significantly change, and then influences main vibration of bar.The elastic reset of another mobile jib 2 is provided in the present embodiment Mechanism, referring to fig. 4, including one with mobile jib cooperation snap ring 6, the tail end of the mobile jib 2 be set in the snap ring 6 and with card Ring 6 is interference fit, is provided in the horizontal direction and vertical direction of the snap ring 6 and resets muscle 60, and the reset muscle 60 wraps First 60a and linear second 60b of V-type are included, wherein first 60a is directly connected with the snap ring 6, institute Second 60b is stated for connecting first 60a and the shell 1.Preferably, one end connection of second 60b described the The other end of one 60a, second 60b connect a fixed ring 61, and the fixed ring 61 is fastened in the shell 1.

It is provided with the first trigger switch (attached drawing is not shown) in the rotating path of the turnbarrel 4 and the second triggering is opened It closes (attached drawing is not shown), first trigger switch and second trigger switch are connect with the control circuit board, when described When the rotation of turnbarrel 4 to first position, first trigger switch is triggered, and the control circuit board controls the electricity at this time Pond component 200 exports the first power W1 to the coil block 3, when the turnbarrel 4 rotation is to the second position, described the Two trigger switch are triggered, and the control circuit board controls the battery component 200 to the coil block 3 output second at this time Power W2 the, wherein W1 >=1.5W2, uses above-mentioned difference in first position and the second position by control battery component 200 Power setting, it is ensured that the application electric toothbrush can guarantee suitable cleaning/massage force when switching different mode Degree.In addition, switch mode and switching dynamics are completed while rotating turnbarrel, because without increasing the upper additional step of operation Suddenly.Wherein it is possible to bump contact be arranged on 4 wall of turnbarrel, so that being rotated into first position and in turnbarrel When two positions, bump contact is contacted with the first trigger switch and the second trigger switch, then triggers above-mentioned trigger switch.
